I keep enterprise WAN, LAN, WLAN, and SD-WAN environments reliable, available, and scalable.

I've supported enterprise network and telecommunications environments for more than 25 years, most recently at AT&T, where I directed day-to-day WAN, LAN, WLAN, and SD-WAN operations across distributed sites.

I maintained network availability above 99% through proactive monitoring, resilient architecture, and rapid incident resolution. I also served as an escalation point for complex incidents and supported F5 Load Balancers to optimize traffic distribution and application performance.

At AT&T, I led network deployments and infrastructure upgrades from design through implementation, maintained documentation and asset inventories, and coordinated technology vendors to improve cost efficiency and service delivery.

Earlier, I provided WAN engineering at CSC for U.S.-based enterprise clients, administered network and server infrastructure at Delphi Mechatronic Systems, and supported IT systems at Eaton Automotive Systems and Servicios Monterrey Telecom.
